To all to 720m it may concern: I

Be it it own that I, Bnxe'r M. iv. HAN- sox, a citizen of the United States, and a resident of Hartford, county of Hartford; 5 Stateof Connecticut, have invented'certain' new and useful Improvements in a Tool and Holder Therefor, of which the following is a specification.

This application is a division of my original application Serial No. 318,532, filed tugust 19th, 1919, patented Dec. 28, 1920, No; 1363.587. The present invention relates to a tool holder and tool particularly adapted for use in metal working machines, such as a vertical die shaper, wherein the tool when moved in one direction operates on the work and when moved in the opposite direction is inactive. The aim of the present invention is to provide a tool and tool holder therefor of this sort having novel and advantageous features of construction.

In the accompanying drawings: Fig. 1 is a front elevation of the tool and holder.

Fig. 2 is a side view'thereof partly in section, and r Fig. 3 is a sectional view taken substantially on a horizontal plane passing through the center of the binding member.

Referring to the drawings in detail, the tool holderis shown as beingin the form of a clapper a, but it is, of course, understood. that-the device of the present inven tion is adaptable for other vuses than in connection with a clapper. b is the tool head of the clapper. 0 denotes generally the tool and (Z is the binding member for securing the tool in place on thehead b.

fitting snugly within the socket providedby the arcuate portions 11, Therear end of the stem 15 is threaded, as shown, to receive a nut 17. The forward end of the binding memberiis 'diame'ti'c'ally slotted as at l8 and the'forward portion'of this slot is of re duced width so as to provide inwardlyfacingshoulders 19. These shoulders 19 are,

inclined downwardly and outwardly with respect to the bottom of the slot 10.

may be of any desired shape, is 'T-shape in. transverse section. The base 21 of the tool is received by the slot 18 andthe forward faces 22 of this base are inclined similarly to and cooperate withthe shoulders 19 of the binding member. The web 23 of the tool extends outwardly beyond the forward face of the head 6 and the front face of this stem is inclined backwardly from its cut: ting edge so that only the cutting edge 20 will engage the work and everything thereabove will clear it. Due to the cooperating inclined surfaces 19. 22, it will be apparent that when the tool cuts into the work, the

effect will be to more securely wedge the tool in placein the holder.

It is-to be understood disclosure of my invention is by way of illustration only and is not to. be taken asrestrictive thereof and that the invention is susceptible of various vmodifications and changes which would be within the spirit of the invention. without departing from the scope of the following claims.

I claim as my invention 1. A tool-holder having a slot provided The tool 0, the cutting edge 20 of which that the present with a socket portion and outwardly flaring portions extending from opposite sides of the socket portion.

2. In combination a tool-holder having a slot provided with a. circular socket portion.

and end portions flaring outwardly therefrom, and a binding member having a head fitting within the socket of said slot.

3. A tool-holder having a face against which a tool is adapted to engage and an opening at an angle to said face. a binding member extending through said opening and having a slot at its forward end provided with shoulders inclined at an angle to said face of said holder,-and a tool having a tapering portion fitting in said slot and. adapted to be clamped between said inclined shoulders and said face of the tool-holder.

4:. Atool holder having a circular socket portion provided with openings in its circumferential wall, a binding member having a head fitting Within said socket, and a tool mounted in said head and having its ends extending into said openings.

5. In combination, a tool holder having a slot provided with a circular socket portion and end portions flaring outwardly therefrom, a binding member having a head fitting within the socket of said slot and a tool mounted in said head with its opposite ends extending into said outwardly flaring end portions. 7 p

I 6. A tool having a forward face, a portion of increased Width rearwardly of said face and a cutting edge at one end of said face; a tool holder, and clamping means engaging said portion of increased width rear- Wardly of said forward face, said holder and clamping means terminating short of said face.

7. A tool'T-"shaped in cross section providing a Web and a base rearwardly thereof and having a cutting-edge at one end of said web, a tool holder, and a clamping member having a slot corresponding in cross section to said tool and receiving the same with the .front face of said Web projecting beyond said holder andclamping member.
